Abstract
A shaft for taking up toilet paper adapted to rotate circumferentially is maintained parallel with respect to supporting devices for supporting toilet paper. A take-up device is provided with fixing devices for maintaining the shaft for taking up toilet paper so as to rotate circumferentially parallel with respect to supporting devices for supporting toilet paper. The position of the shaft with respect to the supporting devices is accurately maintained parallel at all times, and thus, the taking-up pressure of toilet paper can be made uniform. Moreover, even if the shaft is rotated at high speed, toilet paper can accurately be taken up, thereby making it possible to improve the quality of the toilet paper roll.
Claims5
A method of taking up toilet paper in a device that incorporates take-up shaft means, the take-up shaft means including a take-up shaft, for rotatively taking up toilet paper in a roll, first and second support means positioned parallel to and in operative contact with the take-up shaft, and drive means operatively connected to the take-up shaft means for movably positioning the take-up shaft means relative to the first and second support means, said method comprising the steps of:
- rolling the toilet paper on the take-up shaft;
- operatively positioning the take-up shaft parallel to and in operative contact with the first and second support means so as to generate supporting contact pressure against an entire length of the take-up shaft as toilet paper builds up around the take-up shaft at an initial level;
- and
- movably rotating the take-up shaft so as to maintain uniform supportive contact pressure against the entire length of the take-up shaft as the toilet paper builds up around the take-up shaft at the initial level, wherein
- said step of movably rotating the take-up shaft includes movably driving the take-up shaft vertically while maintaining the take-up shaft substantially horizontal and parallel relative to the first and second supporting means.
A device for taking up toilet paper, comprising:
- take-up shaft means for rotatively taking up toilet paper in a roll, said take-up shaft means including a take-up shaft;
- first and second support means positioned parallel to and in operative contact with said take-up shaft, for generating support contact pressure against an entire length of the take-up shaft as toilet paper builds up around said take-up shaft at an initial level;
- and
- driving means for rotating said take-up shaft, and, for moving said take-up shaft means away and parallel relative to said first and second support means so as to maintain uniform supportive contact pressure against the entire length of the take-up shaft as the toilet paper builds up around the take-up shaft at the initial level, the driving means being further for moving said take-up shaft means vertically away relative to said first and second support means, wherein
- said driving means includes first and second drive devices operatively connected at opposing ends of the take-up shaft, the first and second drive devices being operatively connected to each other so as to synchronizingly maintain the take-up shaft in supporting contact parallel with said first and second support means, and a common drive means operatively connected to the first and second drive devices at opposing ends of the take-up shaft, for controlling parallel movement of the first and second drive devices relative to each other so as to maintain the take-up shaft substantially horizontal and in uniform supporting contact parallel with said first and second support means.
